If you have a later version of dos and some program you're trying to run dies
with "Incorrect DOS Version", you can sometimes fool it into running by using
the SETVER program to change the version # that is returned when your program
calls the DOS function got "Get DOS Version". I think the official way to do
this involves an INT21 call with a function code in the A register. Another
possibility is to disassemble the program enough to find where this occurs
and patch it to reflect the version of DOS you have. This is really a bug
since later versions of DOS retain good backward compatibility and the
programmer should really have said:

IF DOS_VERSION > OR = 3.3 THEN CONTINUE

rather than

IF DOS_VERSION = 3.3 THEN CONTINUE

If you need the exact function call details let me know. Also, SETVER only
works if the program uses the "official" method of determining the DOS
version.
